手電筒霍爾元件的設(shè)計(jì)提供了內(nèi)部控制時(shí)鐘機(jī)制，通過定期掃描提供給霍爾器件和模擬信號(hào)處理電路。電路的一部分用于“睡眠”模式下的高電流消耗。周期性地喚醒內(nèi)部電路以根據(jù)霍爾元件的通量確定預(yù)定閾值。磁通中的密度低于或高于BOP/BRP閾值，則驅(qū)動(dòng)輸出晶體管的相應(yīng)狀態(tài)將改變，在睡眠周期期間，輸出晶體管被鎖定在先前狀態(tài)。手電筒霍爾元件它極大地延長了電池的使用壽命，以滿足客戶對低功耗系統(tǒng)的要求。一般使用全極微功耗的霍爾元件，如：如HX6383，HX6382,HX6363,HX6373等全極微功耗霍爾開關(guān)。 </p><p> 雙極霍爾和全極霍爾目前是常用的霍爾開關(guān)，廣泛應(yīng)用于開關(guān)，測速，計(jì)量等應(yīng)用的產(chǎn)品上，但是實(shí)際應(yīng)用中很多人誤將雙極當(dāng)成全極，或者全極當(dāng)成雙極，造成在搭建霍爾電路或者設(shè)計(jì)電路時(shí)的困擾。如今我們就來詳細(xì)講下如何正確區(qū)分雙極霍爾開關(guān)和全極霍爾開關(guān)。1.雙極霍爾開關(guān)雙極霍爾一般都要指定一個(gè)磁極，同時(shí)需要兩個(gè)磁極分別控制高低電平，利用磁場NS極交替來輸出信號(hào)。如S極靠近時(shí)輸出低電平，N極靠近時(shí)輸出高電平。雙極霍爾典型應(yīng)用就是測速或者計(jì)數(shù)。如果磁場被移除，則是隨機(jī)輸出，有可能是打開，也有可能是關(guān)閉。雙極性霍爾開關(guān)特點(diǎn)：穩(wěn)定性好，高靈敏度，寬電壓，一致性好，壽命長。2.全極霍爾開關(guān)全極性霍爾又叫無極性霍爾，其感應(yīng)方式為：全極霍爾不分南（S）北極(N)檢測磁場，磁鐵接近時(shí)輸出低電平，遠(yuǎn)離時(shí)輸出高電平，全極霍爾的感應(yīng)方式與單極霍爾的感應(yīng)方式相似，區(qū)別在于，單極性霍爾開關(guān)會(huì)指定磁極，而全極性霍爾開關(guān)不會(huì)指定磁極，任何磁極靠近輸出低電平信號(hào)，離開輸出高電平信號(hào)。全極霍爾開關(guān)特點(diǎn)：低電壓，低功耗。我司的產(chǎn)品可替代目前市場上大部分allegro、honeywell、旭化成等霍爾產(chǎn)品。</p><div
